Comm Control Head or a Radio Management System (RMS) using the ARINC 429
interface. This pilot’s guide only covers operation using the KFS 599A UHF
Comm Control Head. Refer to the RMS operating procedures on using the KTR
909A in an RMS installation.

allows direct tuning of the frequency. Preset frequency selection (Channel number
displayed in the top line) allows radio tuning using one of the twenty preset channels or the guard frequency. Pressing and holding the CHAN button for more than
three seconds activates the Program Mode.

The Main mode enables receiving and transmitting on the displayed frequency
and is indicated by the MN annunciator. In the Both mode, the receiver scans
the main and guard frequencies. Both the GD and the MN annunciators illuminate
during scan. When a signal is detected, the receiver stops on the active frequency
and illuminates the active frequency annunciator. Scanning will resume when the
receiver becomes inactive. The ADF mode activates an independent ADF receiver.
